1.PK-PD解析とは

 PK-PD解析は,薬物の体内での動きや薬効評価に臨床薬理学理論を利用したものである.薬を投与した後の体内薬物濃度(血中濃度など)の変化を記述する薬物体内動態学(pharmacokinetics)と,体内薬物濃度と薬理反応の強さとの関係を示す薬力学(pharmacodynamics)を統合して定量的に薬効を評価するPK-PD解析は薬物治療に科学的根拠を提供する.薬効と薬物濃度の関係をin vitroあるいは動物実験で評価できる抗菌薬の領域では特にPK-PD解析の臨床応用が進んでおり,実際に重症感染症患者において,PK-PD解析に基づいて投与設計した患者では非実施患者に比べて無効症例数(%)や死亡症例数(%)が低下し,平均入院数の短縮が報告されている1)
